CONDUITING SYSTEM Filed Jan. 10, 1928 2 Sheets-Sheet 2 atl'ozueag Patented Apr. 14, 1931 ISAAC D. GINDHART, JR., OF HARTFORD, NEW JERSEY CONDUITING SYSTEM Application filed January 10, 1928. Serial No. 245,763.

The present invention relates to improvements in a system of conduiting of streets and sidewalks, the main object of the invention being the provision of a novel arrange ment of conduits aligned with and below the junction of the street surface and sidewalks and connected at the intersection of the streets with the mains, that is, water, sewer, electric and telephone lines, whereby it is unnecessary to disrupt the traffic in the streets by excavations, it being possible to have access to the distributing conduits at a point adjacent the curb and under the sidewalk.

Another object of this invention is the provision of a novel construction of curb whereby the base thereof carries the distributing conduits and adjacent each property line a means whereby access may be had thereto.

In the accompanying drawings Figure 1 is a rear elevation of one form of curbing.

Figure 2 is a section taken on line 2-2 of Figure 1.

Figure 3 is a section taken on line 3-3 of Figure 1.

Figure 4 is a view similar to Figure l of a modified construction of the present invention.

Figure 5 is a section taken on line 5-5 of Figure 4.

Figure 6 is a view similar to Figure 2 of still another modified form of the present invention, the slab being foreshortened in the center thereof.

Figure 7 is a diagrammatic plan View of the arrangement of the main for carrying the main conduits and the four corners at a street intersection and showing the diagrammatic arrangement of the present system.

Referring to the drawings, and more particularly to Figures 1, 2 and 3 thereof, the numeral 10 designates the street surface and 11 the sidewalk. The present invention consists primarily of a pre-cast poured-in concrete body 12 which is substantially L-shaped in cross section and is formed at its base 13 with a plurality of conduits 14, such conduits being formed in any desired manner by collapsible or non-collapsible cores or the like and providing means whereby, as will presently appear, the distributing units for electricity, gas, oil, telephone, water and the like may be attached.

Formed in the slab adjacent the property line, or where it is desired to supply service from the conduits, is a hollow portion 15 which is in communication with the conduits l-it and forms, in reality, a junction box whereby the desired connections may be made for the service. There is also provided in the inner face of the member 12 a recess 16 which terminates at the top in a small casing 17 with a removable lid 18. The hollow portions 15 and 16, are, as shown, where desired, lined, as at 19 and 20, by metal, and the entire open front is closed by the relatively T-shaped cover 20" which is secured in place by means of the removable fastenings 21.

As showing one method of service arrangement, there is shown in Figure 2 a valve 22 which is operated through the stem 23 to cut off the valve or switch, the wheel 24 of which is in the small casing 17 and, therefore, accessible from above by merely lifting the lid 18. In case of repalrs or at the initial serv ice, the cover 20 is removed and the service conduit 25 is provided so that the upper end may be connected to the leading-in pipe 26 WhlCh is adapted to be below the frost line and under the sidewalk 11. Where so desired, the sidewalk portion 11 is made removable adjacent the surface portion of the curb so that ready access may be had to remove the cover 20 when repairs are necessary and without destroying the sidewalk, as is the present practice.

In the construction shown in Figures 4- and 5, the curb member 12' is of the usual construction andis used with a base 27 which is laid thereon in the usual mannerrof the mixing of concrete for said bases, the conduits 28 being cast therein by core members and the rods 29 being provided to attach the curb to the base. In this instance the base is provided with the casing 30 having led therefrom beyond the inner face or sidewalk side of the curb member 12 the vertical pipe 31 which is similar to the space 16 previously described, and, therefore, carries'the operatprevious to the setting of the curb 12" 21 ITTK through the small casing 32 ing stem for the valve, which is accessible and the lid 33 parallel with the sidewalk. The house service conduit 34 is also adjacent to but not connected with the curb 12 and is similar to the service pipe previously described.

In the construction shown in Figure 6, the conduit-carrying portion 35 terminates under the street surface and does not extend under the sidewalk, the body l2 being cast therewith and with the recessed portion 36 adjacent the inner edge.

In putting the present invention into practice, the preferred form and arrangement of utilizing the curb-carrying conduit is shown in Figure intersection 37 there is provided a main inlet 38 which is in communication with the main conduit 39 which is placed centrally of one of the streets and previous to the surfacing thereof, the leads 40 extending from the main inlet 38 to the curb line and in communication services, it

- are provided with the respective conduits 14.

It will thus be seen that when it is necessary to make any repairs or install any extra is merely necessary'to excavate under the with traffi'c upon the street.

It will alsohe noted that the present curbs with the curved cut-away portion 41which is especially designed to permit automobiles to approach the curb in a better 7 and closer relation than is the case when the curb is provided with the usual square corner.

As shown in Figs. 4 and 5, the exposed portion 41 of the curb is protected by, a metal rear plate42, which-is held in place and bodily supported by the curb through the anchors 43, which are distorted to provide a better gripping surface in the concrete. This may be applied to the other forms of curbing illustrated, while in Fig. 6, the protector 44 'covers the rcompl'ete exposed end'of the curb 8 and has the apron 45 that extends a distance upon the sidewalk side.
